Purple stems on some seedlings?

GrowAllOutstarted grow question 6y ago

Why would the plants on that edge of the tray have purple stems? Nutrient deficiency? I noticed the one I checked with a purple stem had more roots showing from the rockwool cube than any others... think they're trying harder to get to the juice cause they got shorted?

Purple stems can be a sign of an issue but if they look healthy it's more likely an awesome genetic trait in my opinion. 🤘😤

Early growth sick plants - photoperiod Purpling stem, yellowing leaves, droopy leaves - I’m thinking nitrogen deficiency, but I’m not sure if I should add more nutrients or not to my current solution or if I should flush completely. PPM is at 850, and the PH is 6.3. What are your thoughts? Any GH nutrient schedules?

Purple Stems Hi, Phenos like Sideral do not normally tend to color at the end of flowering (unlike Wedding Cake). However, the stems are already quite purple! I know low temperatures cause stress causing staining, but that much ? UV's and IR's of led light? An excess of something? Thx a Lot �
